How about putting him in my Travel Trailer in a crate? Again, I'm thinking the TT would be hotter than the truck bed would be since there isn't any air moving.
You're exactly right- the trailer would be a worse environment for the dog than the back of the truck. Not just due to ventilation, but because most TT's are designed for good tracking, not passenger comfort. The dog will get his very teeth rattled out of his skull in a trailer! He'd be perfectly fine confined to a cage/kennel in the back of the PU. Just make sure it's properly secured.
And don't let all the Dog Nazis posting here make you feel guilty! Some of them are the same folks that think it's perfectly O.K. to haul
children runnin' around in the back of those crackerboxes commonly referred to as "Class A and/or C Rv's". Go figure! ;)
